It's been a while since Mary Kate Olsen or her twin sister Ashley have made headlines, but now that MK is getting pretty serious in her questionable new relationship, all that's changed!

The former child star, 26, spent Friday cozying up to Olivier Sarkozy, 42, at a New York Knicks game. The couple has been together since the spring, but have yet to make a relationship statement quite this bold!

They spent the game whispering, cuddling and indulging in practically every form of PDA you can imagine. As if it wasn't bad enough that the entire world is now witness to their lovefest, the affection took place with Olivier's two children sitting right beside them!

MK and Olivier have made it six months in their relationship so far, which is probably longer than anyone ever expected -- but how long will they last?!

Do you think these two are in it for the long haul?! Or is it just a fling?
